Abstract: 818,801. Magnetic recording and reproducing apparatus. LOEWE, S. Oct. 3, 1956 [Oct. 5, 1955], No. 30085/56. Class 40 (2). A braking device for magnetic tape reels is intended to prevent the occurrence of loops or undue tape tension. In Fig. 2, the reels 2 and 3 are braked by eccentrically mounted shoes 10 and 11, mounted on a carrier 8, which rotate on contact with the edge of the reels this rotation increasing the pressure between shoe 10 and disc 2 but decreasing the pressure between shoe 11 and disc 3. Rotation of the shoes is limited by the arms 14 and .15 contacting the pins 16 and further movement of the carrier 8 results in equal increases of braking pressure at each shoe. The springs 17 and 18 return the shoes to the central position when the carrier 8 is retracted. If the direction of rotation is reversed so that reel 2 is winding-on then the device operates to apply the heavier braking pressure to reel 3.

Title: Process for the production of valuable hydrocarbon products from distillable carbonaceous materials by treatment with hydrogenating gases
IPC: C10G1/06
Filed: 1935-11-05
Abstract: In the production of valuable hydrocarbons by the treatment of distillable carbonaceous materials with hydrogenating gases at temperatures above 300 DEG  C., and pressures above 20 atms., hydrogenating gases containing oxygen, e.g. electrolytic hydrogen, natural gas, illuminating gas, &c. are added to the carbonaceous materials only after the latter have been heated up to the reaction temperature.  The materials are heated up to reaction temperature in presence of hydrogen free from oxygen, or if gases containing oxygen are used the preheating is carried out in presence of catalysts, e.g. silver chromate, copper oxide, and compounds of metals of the 7th and 8th group, which cause the oxygen to combine with the hydrogen or carbon monoxide present in the gas.  Brown coal mixed with sulphuric acid and molybdic acid and made into a paste with heavy oil is heated to 440 DEG  C. with hydrogen free from oxygen.  The materials are passed into the reaction space heated to 455 DEG  C. and electrolytic hydrogen containing 7 per cent of oxygen is passed through the reaction chamber from top to bottom.  Vaporous products are separated in a separator maintained at 445 DEG  C. 97 per cent of the coal is converted into liquid and gaseous products.  In a further example, mineral oil is preheated with electrolytic hydrogen at 220 DEG  C. in presence of a catalyst obtained by precipitating silver acetate solution with ammonium chromate solution and drying and grinding the precipitate.  The oil is then passed with further amounts of electrolytic hydrogen at 410 DEG  C. over tungsten sulphide.

Title: Improvements in or relating to speed governors
Inventor: ORLOFF GEORGE
IPC: G05D13/10
Filed: 1956-10-11
Abstract: 841,829. Speed governors. ROTOL Ltd. Oct. 3, 1957 [Oct. 11. 1956], No. 31066/56. Class 57. [Also in Group XXIX] A centrifugal governor suitable for mounting in the hub of a variable pitch propeller to adjust the pitch in order to maintain a constant speed of rotation comprises a flyweight 19 mounted so as to respond both to the centrifugal force thereon and to the inertia force which arises during a change of speed. The flyweight is carried by an arm 42 mounted on a fork 21 whereby it may pivot about an axis 20 and the fork 21 is so mounted that it can turn about an axis 22 which is at right angles to the axis 20 and to the axis 140 about which the whole assembly rotates. Thus the flyweight 19 can move, against a speeder spring 38 which is adjustable by a lever 11, in response to centrifugal force and can also move about the axis 22, against either of a pair of springs 28, 29, in response to inertia forces. Both of these movements of the flyweight are transmitted through a ball-ended, cranked extension 40 of the arm 42 to a member 14 which is linked to a valve 18 controlling the pitch change motor. A solenoid 15, which holds the member 14 in engagement with the extension 40, may be deenergized to allow a spring to move the member 14 away from the extension 40 and into engagement with a lever 51 through which the propeller may be controlled manually or automatically for, e.g. feathering the propeller or coarsening or reversing the pitch thereof. Movement of the flyweight about the axis 22 may be dampened by a dashpot. The Provisional Specification describes also an arrangement in which the flyweight instead of being rotatable about two axes at right angles to each other is mounted on a single, inclined axis.

Filed: 1935-04-23
Abstract: A method for the manufacture of briquettes from normally non-coherent substances, particularly coal or lignite dust, in which, after compression has been completed, the pressure is relieved simultaneously from all sides of the compressed mass, is characterized in that, during the relief of the compression pressure, the differences in pressures exerted per unit of surface on the various faces of the briquette are kept smaller than a value which is dependent on the nature and properties of the material to be compressed, by the employment of a matrix the shape of which is defined by the surface of rotation generated by rotating the curve represented by the equation <FORM:0440811/V/1> about the Y axis of the co-ordinate system to which the equation refers.  In this equation x0 and y0 are constants which define the principal dimensions of the mould, and e a and e r are the elongations per unit of length of the material in the axial and radial directions respectively. Specification 427,969 is referred to.

Abstract: 816,218. Variable capacitors. SOLARTRON ELECTRONIC GROUP Ltd. Oct. 24, 1956 [Nov. 2, 1955], No. 31375/55. Class 37. [Also in Group XL (c)] Attenuators, constituted by variable capacitors, and comprising variable electrostatic screens rotating between input and output electrodes, are used in a radar simulator (see Group XL (c)). One such attenuator (see Fig. 3 of the earlier Provisional Specification) comprises holes 22 in a metal drum 21 rotating between input and output electrodes 27, 28. The sizes and spacing of the holes are chosen to produce a desired variation of attenuation. A further attenuator is comprised by holes 23 co-operating with electrodes 29, 30. Suitable attenuator physical dimensions are quoted. Another attenuator, see Figs. 2 and 3, of the later Provisional Specification, comprises coaxial slotted discs 49, 51, both rotating between electrodes 55, 56; motor 65 causes the slots to overlap progressively, thus giving progressively decreasing attenuation. In a modification, see Fig. 4 of the later Provisional Specification, slotted disc 49 is secured to shaft 70 about which the other slotted disc 51 is rotatable; the discs are in frictional engagement. Electromagnet 79, when energized, causes relative rotation of the discs (the relative overlap between their slots thereby progressively increasing) at a rate determined by the ratio of the numbers of teeth on wheels 71, 72.
